UV light source PX-2

xenon lamppulsedminiature

The PX-2 Pulsed Xenon Light Source is a high flash rate, short-arc xenon lamp for applications involving absorbance, reflection, fluorescence and phosphorescence measurements, and especially for measuring optically or thermally labile samples. The PX-2 has an SMA 905 Connector that couples to Ocean Optics miniature fiber optic spectrometers and accessories, including optical fibers, cuvette holders, probes and other sampling optics. The PX-2 operates at speeds up to 220 Hz, offers excellent pulse-to-pulse stability, and has two trigger modes for software control of the flash rate. Any external TTL positive pulse can be used to trigger the PX-2. When it is coupled to a spectrometer, you can easily synchronize operation of both the light and detector. Because it produces a pulsed signal, the PX-2 is less likely to contribute to solarization in optical fiber assemblies, which can occur when fibers are illuminated with signals less than 260 nm. Parts Included The PX-2 ships with the following items:  PX-2 Pulsed Xenon Light Source  12 VDC power adapter  15-pin interface cable Additional Accessories The following are additional accessories available from Ocean Optics that you may need, depending on your system set-up: • USB2000/PX-2 adapter (USB-ADP-PX2) • Replacement bulb (PX-2-B) ► Procedure Follow the steps below to connect the PX-2 to a USB2000/HR2000 Spectrometer: 1. Remove the PX-2 from the product packaging. 2. Connect the USB-ADP-PX2 Adapter to the spectrometer’s accessory connector. For USB2000+/USB4000/HR2000 Spectrometers with the 20-pin connector, skip the first column of pins (A1 and A2 on the right) when plugging in the adapter.
